This is a prospective, open-label, randomized controlled trial conducted at Lattakia University Hospital (Tishreen University), aiming to evaluate the efficacy of Ursodeoxycholic Acid (UDCA) as an adjuvant to triple phototherapy in the management of indirect hyperbilirubinemia in neonates ≥34 weeks of gestation. Eligible neonates will be randomly assigned to one of two groups: Group A: continuous triple phototherapy only Group B: UDCA (10 mg/kg/day in two oral doses) in addition to triple continuous phototherapy. Stratified randomization will be applied according to etiology (hemolytic, non-hemolytic, G6PD deficiency). The primary outcome is the rate and time of decline in total and indirect serum bilirubin to below phototherapy thresholds, monitored every 12 hours until discharge. This trial seeks to determine whether UDCA may reduce phototherapy duration or enhance bilirubin clearance in a safe and effective manner. Although this is an open-label trial for care providers and participants , the statstican conducting data analysis will be blinded to group allocation to reduce assessment bias.
